Calculating factorial of a given number

Report a typo

Create a Java program that prompts the user for an integer 'n' and prints the factorial of 'n'. Your program should consist of a main method where all your logic resides. Assume the input integer 'n' is non-negative. The main method should read from the standard input and print to the standard output. For example, if the input is 5, the output should be 120 since 1*2*3*4*5 = 120.

Sample Input 1: 

5

Sample Output 1: 

120

Sample Input 2: 

0

Sample Output 2: 

1
Write a program in Java 17
import java.util.Scanner; // 3.1 Import necessary library

public class Main { // 3.6 Always use 'Main' as class name

// 3.0 No method main code here, user write their own

public static void main(String[] args) {
// 3.2 Create a Scanner object
Scanner scanner = new Scanner(System.in);

// TODO: 1. Ask user for an integer 'n' using scanner.nextInt()

// TODO: 2. Print the factorial of 'n'

scanner.close(); // Always close the scanner when done
}

}
